Description
Technical field
The present invention relates to a kind of air compressor, refer to that one has manometric air compressor especially.
Background technique
Early stage air compressor, refer in particular to and be used in automobile tire, the mini air compressor that the inflation such as the article such as air cushion purposes uses, its body is only provided with two and gives vent to anger manifold (duct) on gas storage seat, one manifold is in order to install the box-like pressure display table of circle, another manifold is provided with the flexible pipe of valve in order to be engaged on one end, this valve is then connected to object to be inflatable product, for example automobile tire, the compressed air delivery that produces is operated to object to be inflatable product by air compressor, to reach the object of inflation, pressure display table then can provide user visual force value instantly, using the foundation of the Security as manipulation inflation action, the pressure display table that this kind of known circle is box-like, it belongs to use the mechanical indicating pointer type pressure gauge of Baden's pipe made by (BurdenTube) principle, because this kind of Baden's tubular type pressure display table needs more precision components, but the precision components used is also very easily in being damaged, cause losing precision when measuring, therefore, the utilization benefit of Baden's tubular type pressure display table is unevident.In order to overcome the use disappearance of Baden's tubular type pressure display table, a kind of new case of practicality of inflator pressure display device is disclosed at present at Japan's patent gazette, the practical new case of Japan logs in No. 3185073 (U3185073), the pressure display equipment of this creation mainly has a hollow tube, a sheath and an air input joint is provided with in body two end, plane plate and a spring that one can carry out straight line motion in this body is then provided with in body, then a scale is separately provided with outward in body, on body most distinctive be provided with one can the relief hole of pressure release, after pushing block accepts the pressurized air of inflator, plane plate compressible spring also carries out straight-line displacement, when inflation pressure exceed the highest setting pressure time, relief hole set by hollow tube can discharge excess pressure, the inflatable safety of thing is inflated with protection, this known disclosed creation is in structural design, although breached known Baden's tubular type pressure display table, but because its active area as the relief hole of overvoltage safety protection is too narrow, it is the circular hole in point-like, because the aeration speed of inflator is quite fast, therefore this relief hole is not good in the usefulness of moment pressure release, on the other hand, this relief hole also very easily by the dirt dust that circulates and inflator body used increase the lubricant residue of smooth and easy running the dust that mixes blocked, may reduce or lose the using function of pressure release, another aspect it should be noted that one end of streak-like planar plate body is that the movable pushing block that is connected to overlaps ditch place, the other end is central perforation place worn of sheath that stretched through, when under the impact that pushing block and spring vibrate in inflator high frequency jointly, this one end that plane plate is connected with pushing block is easier to get loose, skew, cause the other end of plane plate can form the displacement movement of deflection jointly, the frictional force that the travel path of this kind of skew can cause being placed through between both plate body surrounding in sheath perforation and perforation increases, very easily wear and tear and bore a hole perisporium and expand this perforation field, to be worn and the perforation of enlarged-area more can cause rocking of plane plate, vibration, both plane plate and pushing block is more easily facilitated to produce the phenomenon getting loose or come off completely jointly, so just there is obstacle in pressure measurement or lose accuracy, again on the one hand, the length of the straight-line displacement of plate body adds the formation length of scale, and it also can increase the length penalty of whole display device in spatial design, is also that it needs thinking and improves part.
The present inventor still has thoughts on practical new No. 3185073rd, the case (U3185073) of published Japan to use disappearance, actively researched and developed improvement, phase develops one can allow air compressor need not add overpressure safety valve in addition, and when force value reaches set safety pressure maximum value, can react rapidly and the product of excess pressure of releasing moment, therefore this case produces.
